The list will not open when in the parentwindow a Ctrl with a FlatSpin in the Paint event is used.

Why do you want to use a Flatspin in the Paint() method anyway?
When you Add() the flatspin to the parent Ctrl, it will be added to the Child Ctrl list. So, it's paint() method is already invoked and the flatspin gets refreshed when you manipulate its values (e.g. text).

In DateTimeCtrl.cpp it is defined as:

void FlatSpin::SetText(const String& s)
{
	text = s;
	tsz = GetTextSize(text, font);
	Refresh();
}

That's probably why it won't work. It already gets refreshed when you set the thext of SpinCtrl.

Instead you should define it as,

MyCal::MyCal()
{
	Add(spin_year);	
	String year = AsString(2008);
	spin_year.SetText(year);
};

This will solve your problem. And you can use "spin_year.WhenAction = blabla()" or other custom Callbacks to handle it's events.
